DDR2-RAM and TSE - How to increase data-rate?

Hello, 

 

I've the following design on my Cyclone III Dev. Board: 

 

- NiosII writes data to DDR2-RAM 

- When writing data finishes NiosII activates SGDMA to put all this data to TSE. TSE then transmitted this data... 

 

First I used OnChipMemory instead of DDR2-RAM. I reached an output-rate at TSE round about 80MBytes/sec. 

But now I want to use DDR2-RAM with DDR2 SDRAM High-Performance Controller because I have much more data to store. I only reached an output-rate at TSE round about 17MBytes/sec. 

 

What can I do to increase the output-rate of TSE with using DDR2-RAM? Is there any possibility? 

 

Thanks for every hint!
